Climate change and disease outbreaks, 2009-2018. Global map of sea surface temperature (SST) anomalies and patterns of worldwide infectious disease outbreaks in the period 2009 to 2018. This visualization shows the variability in SST anomalies with the associated ENSO (El Nino-Southern Oscillation) index timeline. Weather changes associated with the ENSO phenomenon result in rainfall, temperature and environmental anomaly conditions that help produce outbreaks of infectious diseases. The eleven diseases mapped on this visualization are: chinkungunya, cholera, dengue virus, hantavirus, plague, respiratory illness, Rift Valley fever, Ross River virus, St Louis encephalitis, tularemia and zika virus. The map combines epidemiological data and satellite data.
